A colour space is a specific organization of colours. In combination with physical device profiling, it allows for reproducible representations of colour, in both analogue and digital representations. The colour spaces most commonly encountered in photography are Adobe RGB and sRGB.

More generally, what is the nature of the gamut? Primaries as peak sensitivity don't behave the same as primaries for mixing output.
I suppose this is necessary to know for RAW importing and would be ...

To pay the bills I am a developer first, web stuff mainly. All of my photography, so far, has just ended up on the web, and I don't think that that will change anytime soon.

What colour space does Lightroom use when you load an Adobe RGB or SRGB tiff/jpeg file into the Develop module? The reason I ask is because I was told that the develop module always uses the ProPhoto ...

There are a couple of RGB color spaces out there - LStar-RGB.icc and ProStarRGB.icc- that use the L* tone response curve. What's the supposed advantage of using the L* TRC over using a gamma curve as ...
